Seabrook Playground

The zipline alone makes this place worth the trip — kids will lap it over and over while you actually get to sit down on one of the benches and breathe for a minute. It’s fully fenced, which is a genuine relief when you’ve got younger ones in the mix, and the climbing structure keeps the older kids busy enough that nobody’s bored. Restrooms and parking on-site means you’re not doing any kind of logistical juggling just to make a playground visit work. Locals treat it like a bit of a gathering spot, and honestly, for Copalis Crossing, it punches above its weight.
